My truck's gas mileage has been dropping. After investigating a number of YouTube video's I suspect the O2 sensors have become clogged with carbon. Most of the video's I've seen show spraying them with some kind of cleaner, be it "Carb Cleaner" or some other aggressive chemical. They all claim to improve gas mileage back to around factory original mileage.
NO, I'M NOT LOOKING FOR SOMETHING TO GIVE ME 100 MPG. Just tired of seeing 15 to 16 MPG on a vehicle that used to get (at best) 25 MPG (Typical highway 22 MPG, city 19 MPG).
Gasoline producers run two grades of fuel. One formula is meant for winter driving. Less polluting but also reduced mileage. Even then, 18 MPG city was something I'd normally see. As of this year mileage has been dropping like a fly. I could replace the "UpStream" sensors at a cost of around $200 each. For a couple 10 spots I can get an ultrasonic cleaner. HOWEVER, I don't want to destroy the sensors either. So if anyone has experience or advice - please chime in.
